UNITED STATES PATENT OFFICEQ VILLIAM KIRKOOD, OF GUELPH, ONTARIO, CANADA.

SECTONAL WAATER-H EATER.

SPECIFICATION forming part of Letters Patent No. 388,418, dated August 28, 888.

Application filed December l5, IESI. Serial No. 257,957. (No model.)

.To @ZZ whom, t may concern.:

Be it known that I, WILLIAM Krnxwoon, of the city of Guelph, in the county of Wellington, in the Province of Ontario, Canada, steam-fitter, have invented certain new and useful Improvements in Sectional Water- Heaters, of which the following is a specification.

The object of the invention is to design a cheaply-constructed sectional water-healer, in which a perfect circulation is maintained through independentv tubes arranged so that they will be surrounded by the heated gases arising from the combustion-ohamber of the furnace; and it cousists,essentially, of two vertical chambers arranged parallel with each otberandsuitably partitioned, horizontal tubes being connected to the walls of and arranged to connect with the interior of one chamber which is bridged by horizontal tubes of a smaller diameter connected to the walls ofand communicating with the interior of the other chamber, the said tubes extending into the tubes connect-ed to the wall of the former chamber, so that the fluid entering the latter will flow through the larger tubes and iind its way through the smaller tubesinto theother chamber, the whole being arranged in detail, substantially as hereinafter more particularly explaiued.

The drawing is a sectional perspective View of my improved waterheater.

In the drawing, A is the feed-water pipe, which communicates with a chamber, B'. This chamber is formed between the walls a and b, which extend the full height and width of the heater.

d is a vertical wall or partition located between and corresponding with the walls a and b, so as to make a division and form the two parallel chambers B C.

D represents a series of horizontal tubes closed at one end and each screwed or otherwise secured to the inner walls, a, so that the interior of all the pipes will communicate with the chamber B. l

E represents a series of tubes smaller in diameter than the tubes D and open at both ends. Each of these tubes E extends into one of the tubes D, and is screwed or otherwise secured into the wall d,so that it will extend across the chamber B into the tubes D and form a connection between the interior of the chamber C and the interior of each of the tubes D. y

In order to secure complete circulation through the heater when it is to be used for warming water, I form horizontal partitions across the chambers B and O,the effect of which partitions will be understood when I explain the operation of my heater. The wall d might extend the full length of the wallsa and b; but in the drawing I have shown it commencing at a pointjust below the lower row of tubes D, and at that pointhave formed a horizontal partition e, extending across the heater and closing the bottom of the chamber B.

I do not claim anything peculiar in the arrangement of the furnace; but I may say that F represents the grates of the furnace and G its door. II and I are two pipes arranged to fit around the wall of the furnace and connected together at one end, while their other ends are connected to the walls a and communicate with the interior of the chamber C, as shown. rlhe water which enters through the pipe A will naturally flow through the pipes H and I and ascend to the partition f, extending across and dividing the chamber C. As the threelower rows-of the tubes E communicate with this lower portion of the chamber C, the water will naturally flow through them and find its way out of their opposite ends into the tubes D and through them-into the chamber B, and by following the course indicated by arrow will return'through the next rows of tubes D and E back into the chamber C above the partition f, and then back through the tubes E D into the chamber B above the partition g, and so on until it reaches the dome J, from which it is carried in the usual way.

In the illustration of my boiler I divide the chambers B C, so that the tubes D E shall be in sets of three; but I do not confine myself to any particular number of divisions, as the number may be altered to suit the opinion of the paticular manufacturer making the boiler.

In order that the tubes D may be readily cleaned, I provide a door, K, which may be readily opened to expose all the tubes, which may thus be easily cleaned of any deposit left on them bythe heated gases ascending from the furnace.

IOO

It will be observed that by my arrangement of the tubes the course of water is alternatedthat is,in thelower group the Water enters the tubes E and passes out the tubes D, While in the next group the water enters the tubes D and passes out the tubes E, and so ou. This is important.

Vhat I claim as my invention is l. Twovertical chambers arranged parallel with each :other and suitably partitioned, horizontal tubes being connected to the walls of and arranged in groups, as described, to connect with the interior of one chamber, which is bridged by horizontal tubes of a smaller diameterV connected to the walls of and communicating with the interior of the other cham ber, the said tubes extending into the tubes connected to the wall of the former chamber, so that iluid entering the latter' will liow through the larger tubes and [ind its Way through the smaller tubes into the other cham ber in one group and vice versa in the next group, substantially as and for the purpose specitied.

2. Two vertical chambers arranged parallel with each other and suitably partitionefhhorizontal tubes being connected to the Walls of and arranged in groups, as described, to connect with the interior of one chamber, which is bridged by horizontal tubes of a smaller diameter connected to the Walls of and communicating with the interior of the other chamber, the said tubes extending into the tubes connected to the Wall of the former chamber, so that fluid entering the latter will Y ow through the larger tubes and ind its Way through the smaller tubes into the other chamber in one group and Vice versa in the next group, in combination with the dome J, into which the said chambers communicate, substantially as and for the purposes specified.

3. The tubes D, closed at one end and connected at their opposite open end to the Wall a,and containing smaller tubes,E,open at both ends, but connected to the Walls d at one end, so that the chambers B C will be connected through the tubes specified, in combination with horizontal partitions formed across the chambers B C, and alternating, as shown, and the pipes H Larrauged beneath the lower partition around the furnace,substantially as and for the purpose speciiied.
